.` following is a specification, reference being had to the accompanying drawings.

My invention relates to car doors, and especiallyto do withdoors of the type known as grain-car doors designed to close the 4` ylower portion of the door openinggofabox car to permit offits being'filledfto'a greateror ljess'extent with-grain. The obj ect of my invention isv to provide a new and improved lcar sdoor bywhich the Ycapacity of the car may be increasedand which may readily' -be manipulated to move it either into. operative or inoperative posi-, tion also to provldef'a' new and'improved metallic car door meeting'the'jrequirements essentialffor its use as. `afgraifn-car door. I

. accomplish theseohjects as illustrated in the drawings and as hereinafter described. I

What I regard as newT is setforthin the claims.

lfit, as Ashown 2.. I. On its outer face saidA door is provided with one or more pieces or girders 14,` which .extend longitudinally of the door., i. e. parallel, or approximatelyA so,

with the u l per and lower edges thereofand aref hinge tothe door by hinges 15, as

, shown in Fi s.- 1 and 3, so that eachof said girders may e turned. about an axis parallel with itsl length to permit of its being folded down atright anglesto the plane of the door, or up against, the door,

The two positions of the girder are shown, respectively, in

r4dotted linesin Fig.` 4. When the girder 1'4- is linits o erative osition it is at right angles, or su stantia y so, to the d or 10, and .its'ends it in the recesses I3, as'shown in Fig. 4. Said girders', therefore,lserve 5to brace the door against internal pressure and also hold it inoperative position' by reason of their. engagement with the recesses .-13.' I

prefer to provide the door with two girders,

`ut` the number may be varied to meet spe.-

jcialconditions.

- The door is supported'by hangers 16 which susdpend it from ya'traclrll 7, as shown in Figs. 2 .an `section and the hanger 16 at its-u per end is isa partial view of a box car, illustrating the ,oter side of my improvedoar door opera- 30 y3. The track 17 is rectangular in crossprovidedwith a hook 18 which ooks over fthetrack, as shown in Fig. 6. The hanger is also provided with an offset portion 19,

fwhichextends under the trackso that Vthe 'dooris lnot only suspended under the track -but a fy considerable 'u ward movement of ltheghan'ger is prevented). 4the hanger isf made oftwo parts, which are' connected bya pivot 20, the up er ortiony l.In` its best form 16a of the hanger being'thus capab e'o swing-V ing'vrelatively t0 the lower portion thereof.

asis sometimes desirable in starting it, ,this

ment o the upper andlower members of each hanger, the upper portion of each hanger turning slightly on the track. 'This adjustment is'not 'of anyg'reat extent as the upward movement of the door is'very slight. "The lower portion O f thehan erv is iXedly se- I the door, pref-` 'cured to the upper portion o erably by 'rivets-:the lower end of the hanger being bifurcated so as to provide a more secure connection.

21 indicates auxiliary doors at the corners of thedoor 10 for releasing the ressure upon the door before opening it. aid auxiliary doors are fittedlin slides 22, as shown in Fig. 2, sothat they may be raised or lowered at pleasure. y

23 indicates guides for the lower edge of the i when the door is closed.

girders into operative position when the door',

When the'dooris in inoperative position, the girders 14 are folded up against the inner face of the door 10, and the door is slid back away froml the door'openinglying closely against theside of the ear so that it does not interfere with the use of the ear for any de-l sired purpose- When,A the car is to be used.

for lpadin grain, the dooris slid into position opposite t e door opening and the girders 14 arefolded down to their operative position, at which time their ends enter the recesses 13. The Acar may then be filled with grain, or other vsimilar freight. The girders do not prevent -the. door from being moved endwise.

when the carl is empty since. the door may thenbe easily s run far enough away from the posts to ena le tie girders, when turned up out of o erative position, to pass the door posts. fit is necessary-in releasing the door to lift it to ajgreater or less extent, this may be accomplished by reason of the pivotsV 20 with which the door hangersare provided. In Ordes.` to insure the folding down of the is to be closed, I providesprings 27 preferably carried by the girders, but which, if desired, may becarried'by the door. Said springs are Aarranged to be put under tension when the girders are folded up against the door andare held so when the .door is in inoperative-v-p'osition. When, however, the door is `moved out into operative position, the girdersl are released and Athe springs' automatically cause them to move downward into operative position. l That which I claim as my invention, and desire to secure by Letters Patent, is,-

1. A car door having a girder adjustably securedV thereto and extending longitudinally thereof, said girder bein ada ted to be turned about an. axis aral el Vwit its length so as lto lie at an ang e to the door or to be .55

folded thereagainst, said girder when turned at an angle being arranged to present a greater width substantially erpendicular to the plane of the door 'than wlhen in its folded position.

2. The combination of a car having door geste at opposite sides of the door opening, a

' oor, the: ends ofwhich'bear against said posts, and a longitudinal girder adjustably secured to the oor, said girder being ar-.g

ranged to be turned about'an axis parallel with its length so as to lie atan angle to the door or to be folded thereagainst, said girder when turned at an angle being arranged to present a greater width substantially erpendicular to the plane of the door than w ien 1n its folded position.

3. The combination of a car having door posts at opposite sides of the door opening, a

door, the endsfof which bear against said posts,- and a longitudinal girder adjustably secured to the outer side of the door, said girder bein arranged to be turned about an axis paralle with its length so as to lie at an angle to the door or to be folded thereagainst, said girder when turned at an angle being arranged to present a greater width substantially perpendicular to the plane of the door than'when in its folded position, said posts having recesses to receive the ends of said girder.

4. The combination of a car having door posts at opposite sides of the door o eninfr, an endwise-movable door, the ends o whidli bear against said posts, a longitudinal girder adjustably secured to the door on the outer side thereof, said girder being arran ed to be turned about an axis parallel with itslength so as to lie at an angle to the door or to be folded thereao'ainst, said girder when turned at an an le eing arran ed to present a greater 'wi th substantial y perpendicular to the plane of'the door than when in its folded position, said posts vhaving recesses to receive the ends of said girder. I

5., A cardoor having a girder adjustably secured thereto and arranged longitudinally thereof, said girder bein arranged to be turned about an axis ara lel with its length so as to lie at an ang e to the door or to be folded thereagainst, said girder when turned at an` langle being arranged to present a greater width substantially erpendieular to the plane of the door than w en in'its folded position, and means for automatically moving saidgirder to its angular relation with the door.

6. A car door` having Ia girder adjustably secured thereto and arranged longitudinally thereof,4 said girder beiner arranged to be turned about an axis ara lel with its length so as to lie at an ang e to the door or to be folded thereagainst, said girder when turned at an angle being arranged to present a greater width substantially perpendicular to the plane of the door than w renin its folded position, and a spring for automatically moving said girder to its angular relation with the h door.
